Merchantville, Null, assignors to Weyerhaeuser Company, Tacoma, Wash, a corporation of Washington Filed Sept. 28, 1964, Ser. No. 399,445 8 Claims. (Cl. 229-17) This invention relates to a composite package having an inner liner with a nozzle and an outer protective container in which the nozzle may be fastened, and specifically relates to a flap construction on the outer container which allows the nozzle to extend through and be fastened to the outer container.

A composite package is useful for transporting'many goods, especially liquids. The goods are held in an inner plastic liner which has a nozzle and stopper construction for dispensing the goods from the liner. The liner is within an outer container which protects the liner during storage, transportation and use. It is usual practice for the nozzle and stopper to be within the outer container prior to dispensing the material from the liner. This allows the container to be stored, stacked and transported easily. When the material is to be dispensed, the outer container is opened and the nozzle is pulled from the container and fastened to the container so that it will not be pushed within the container during use.

Containers which allow the nozzle and stopper to be inside prior to use are usually cumbersome or uneconomical. They are cumbersome because they require either a specific orientation of the nozzle to the container in" order to lock the nozzle to the container, or they require an end of the container to be taken apart and re-formed in order to fasten the nozzle to the container end wall. They are uneconomical because they have a false end wall or second cover over one end of the outer container to protect the nozzle which extends through and is-fastened to that end of the container.

It is an object of the present invention to provide an outer container for a composite package which is inexpensive and which allows the nozzle to be fastened to the outer container simply and easily. These and other objects of this invention will be readily understood upon the reading of the following specification in conjunction.

with the attached drawings.

FIGURE 1 is a top plan viewof a blank of thepresent carton.

FIGURE 2 is an isometric view of the container formed from the blank of FIGURE 1. Portions are cut away to show details of construction.

FIGURES 3-5 are isometric views showing the nozzle being attached to the outer container. Again, portions of the container are cut away to show details of constructlon.

The container has a top panel 10, a side panel 11, a bottom panel 12, a side panel 13 and a glue flap 14. These panels are connected along the score lines 15, 16, 17 and 18. In the finished carton, the glue flap 14 is glued to the underside of panel as shown in FIGURE 2.

End closure panels 19, 20, 21 and 22 are connected to the respective panels 10, 11, 12 and 13 along the score line 23. In the completed carton the end closure panel 22 is folded inwardly around the score line 23 until it overlays the bottom opening, the end closure panels 19 and 21 are then folded inwardly around the score line 23 until they overlay the panel 22, the end closure panel is then folded inwardly around the score line 23 until it FIGURE 3.

The composite container is formed by interfolding the end closure panels 19-22 to close one end of the container, inserting the filled liner 28 with its nozzle 29 and stopper 30 into the container, and closing the other end of the outer container.

The panels forming the other end closure, panels 31-34, are connected to the panels 10-13 along score line 35, and the end is closed by bending panels 31 and 33 inwardly around score line 35 until they overlay the liner, and thereafter bending panels 32 and 34 inwardly around score line 35 until they overlay panels 31 and 33. The panels are held in place by tape 36.

This packagehaving the liner 28, nozzle 29 and stopper 30 insidemay be transported and stored easily because of its regular shape. At the time the material is to be dispensed from the liner 28, the nozzle 29 and stopper 30 will be pulled from the interior of the outer container and fastened to the outer container. This is facilitated by the construction of the end closure panels 33 and 34.

The outer end closure panel 34 has a perforate line 37 which defines a flap 38 in the panel. When the carton is to be used the flap 38 is pulled from the plane of the panel 34 and bent outwardly around the score line 35. Although the score line 35 forms the most convenient hinge for the flap 38, it is possible to have other hinged connections for the flap depending upon the placement of the flap in the panel 34.

Following this, a cutout 39, defined by a perforate line 40 in the locking section 41 of the flap 38, is removed from the flap to form an aperture 42. This is shown in As may be seen, the aperture 42 extends to one side of the flap 38. The nozzle 29 and the stopper 30, which are aligned wtih the flap 38 when placed in the container, are pulled through the aperture 43 in the inner panel 33. This aperture, which is aligned with the aperture 42, is larger than the nozzle 29, allowing the nozzle to be pulled through the aperture. The aperture 43 is also larger than the aperture 42, which is the approximate size of the circumferential indentation 44in the nozzle.

The indentation 44 is used to fasten the nozzle to the outer container. When the nozzle 29 is in its outermost position, the flap 38 is bent inwardly around the score line 35 and the aperture 42 is placed over the indentation 44, attaching the nozzle 29 to the flap 38. The outer end 45 of the flap 38 is then attached to the container by being bent inwardly around the score line 46 and being forced through the slot 47 in the panel 33. The attachment of the flap 38 to the panel 33 is aided by the notches 48 at the extreme ends of score line 43.

Thus, the construction of the inner and outer panels 33 and 34, which are at right angles to each other, allows the nozzle 29 of the inner liner to be attached to the flap 38 of the outer container by providing a large aperture 43 in panel 33 which is aligned with a smaller aperture 42 in the locking section 41 of the flap 38; and allows the flap 38 to be attached to the panel 30 by providing a score line 46 which divides the flap 38 into a locking section 41 and an outer section 45 and which is aligned with a slot 47 in the inner panel 33 in the finished container. The present construction is also economical because the flap 38 and the cutout section 39 are defined by perforate lines 37 and 40, respectively, in the outer panel and, therefore, form a part of the outer panel during transportation and storage. Thus, the flap and cutout section are used both to protect the inner liner during transportation and storage and to attach the nozzle of the inner liner to the outer container during use.

While specific details of the preferred construction have been set forth, it will be apparent that many changes and modifications may be made herein without departing from the spirit of the invention. It will, therefore, be understood that what has been described herein is intended to be illustrative only and is not intended to limit the scopeof the invention.
